Takealot is not taking accountability for their mistake. Poor customer service!

I received a pot set on Tuesday 26th (after waiting a week with much excitement). The pots arrive and I'm very happy but notice that the 2 plastic lids was not in the box. Immediately I have to search for Takealot customer care, because that option isn't readily available on the app, so I googled the number. A woman helped me and said she would organize a return and an investigation would be opened. Upon repacking the box, I received an email asking me to unpack all the items to take photos of what is in the box, and also of some barcode on the box. I sent this later that same day and was left without any response until I followed up 2 days later, just to hear that only now they are escalating the problem to the relevant department. This is ridiculous, this isn't my mistake. I just want what I paid for and I specifically chose this pot set for the plastic lid feature that seals the pot to put in the fridge - and now i have to wait so long for this mistake to be resolved?? Am I expected to NOT use these pots while I wait for Takealot to fix this issue??
